…it came as a shock to learn that AT&T chairman and CEO Randall Stephenson would actually praise the FCC for anything.

At the Goldman Sachs Communacopia Conference this week, Mr. Stephenson said he "applauded" the FCC's decision to take another look at how much wireless spectrum a mobile carrier should be able to acquire.

Of course, his shifting stance toward the FCC has less to do with making sure the smaller carriers aren't left wanting, but more with guaranteeing that AT&T's main rival, Verizon(NYSE: VZ), doesn't get the opportunity to become even more spectrum-rich.

Indeed, the day after Stephenson spoke, Verizon's CFO Fran Shammo told the Communacopia audience that his company was sitting on enough spectrum to keep it in business comfortably for another four or five years.

Two -- five -- 24That's 2 million iPhone 5s pre-ordered in the first 24 hours, a new iPhone sales record, according to Apple(Nasdaq: AAPL). Last year's release of the iPhone 4S sold only half that number.

Those sales will certainly help lift revenues for AT&T, Verizon, and Sprint Nextel(NYSE: S). Smaller carriers, such as Leap Wireless' Cricket brand and Alaska Communications, will get the iPhone 5 in a week.

Will the real iPhone carrier stand up?The carrier that is the leader in iPhone activations, according to a report from Consumer Intelligence Research Partners, is AT&T. Verizon leads in Android phone activations.

AT&T got a huge head start when it became the first -- and exclusive -- iPhone carrier. More than half of AT&T's activations are for the iPhone, and another third are for Android phones. The rest is made up of BlackBerrys and feature phones.

Though Verizon's iPhone activations comprise only one-quarter of its sales, there's a good chance that fraction may get larger. The iPhone 5 being LTE-capable may give the edge to Verizon, with its larger LTE network. Until AT&T can boost its LTE coverage, customers seeking LTE speeds for their iPhones may create an exodus to Verizon.

Is this RAZR sharp enough?Next month, Motorola will be bringing out what it hopes to be a worthy iPhone rival, the RAZR i. The new phone touts a 4.3-inch edge-to-edge display that is 15% larger than that of the iPhone 5. Motorola also says it will have a more powerful battery than the iPhone.

But -- and a big one -- the RAZR i may also sport an i in its name, but it's missing three other letters that the iPhone 5 can claim: L, T, and E. Without LTE capability, the RAZR i may be able to hold its own with the older models of the iPhone, but against the iPhone 5? Probably not.

Don't let the door hit you in the backOnce upon a time (2008), Time Warner Cable paid $550 million for 46.4 million shares of Clearwire(Nasdaq: CLWR). These days, those shares are only worth around $73 million, and the cable company is now ready to cut its losses and sell, according to a regulatory filing.

TWC is one of several cable companies who bought into Clearwire with the intent of using its wireless spectrum to get into the mobile communications business. Those cables include Comcast and Bright House Networks. After Verizon's spectrum-for-co-marketing deal with those companies was approved just weeks ago, Clearwire's resources have lost their allure to TWC.

Clearwire, though, isn't throwing in the towel. The company's CFO, Hope Cochran, said at the Goldman Sachs Communacopia Conference that Clearwire is going to begin work on its LTE network this quarter, and will really get moving over the next three months.

This new network will not come soon enough for Clearwire. With its long-term partner Sprint throwing fewer wholesale WiMAX customers its way, Clearwire has to get its own 4G LTE network up and running to provide services for customers such as Leap Wireless, with which it signed a five-year wholesale agreement.

The Trojan e-readerWal-Mart has banned Amazon from its stores. The brick-and-mortar retailer finally realized that what the online retailer was really selling was not the Kindle, but whatever media the Kindle displays.
